Are you a “newbie” or “newie”?

Are you a “newbie” or “newie”? And is “behind the scene” an obscenely frequent example of poor grammar?

Some errors in English (and I don’t mean typos) come from little things, like using an “s” when you shouldn’t (and vice versa), using a wrong letter in a word, or leaving out an important word. They are errors nevertheless, and can give the impression that the speaker or writer does not know the finer points of the language.
